Is this possible: code a metadata data collection app

[cyber3d]

Is it possible to code a program/app that would scan all my images, read the metadata and give me an instant readout of each item and the percentage of use for each?

I want to add a category to my blog that shows the lenses I use and at what percentage I use them, same for ISO, f-stop, etc...

Want to add something fun to show on the blog. A realtime widget sort of.

I remember reading somewhere about a program capable of doing exactly that (telling you percentages by scanning your collection, which lens you use most, which aperture, shutter speed, etc.) but I can't remember where. Someone here at dps probably knows about it.

I had a LR3 plugin that plotted that stuff, I think it was
Jeffrey Friedl's Blog Jeffrey’s “Data Plot” Lightroom Plugin.
For a standalone version, Exposure plot; Jeff links to it on the blog.

The LR Library filter (Available at the top of the page in the Library Module) gives you similar information. And obviously there's the answers above mine.

So the short answer to your question is "yes, it is possible" however whether anyone has written a program that you can tie into your blog I can't answer.. But if you find one, let me know, I'd love to access that kind of real time data.

You certainly could do and you could do it with PHP which means it could read from a folder of images on your website if you wanted it to and make the list completely dynamic.

If not, you could still do it in PHP and convert it to an executable app.

In fact, in an effort to avoid work because this sounds more interesting, I might give it a go later on today :P

For Wordpress users, metadata is inserted in the database for any image you upload through Wordpress. Creating a plugin should then be as simple as running a query on the database and displaying the results. Of course this would only work on the images you actually upload to your blog.

Well you might find this function useful Biomech. It certainly shouldn't be too difficult to save this info into a database and make it searchable.

PHP: exif_read_data - Manual

If you write something, would you be kind enoug to share the source code? I'd be really happy to hack a couple of pages on my site to get this kind of info.

Of course, if Wordpress is already doing this, (probably using this function) then it's just a case of reading the data from SQL.

Had a really shit day so didn't bother. But certainly, if I get something going, I'll be sure to share

You're a good egg biomech!

I think the tool you're looking for is ExifTool. It's fairly widely-used, and I believe there are some GUI front-ends for it, too.
